[PATCHv5 0/8] perf tool: parser generator for events parsing

[Jiri Olsa <jolsa@redhat.com>]

hi,
here's new version of event parsing patchset.

I saw Arnaldo already sent patches 1-3 to Ingo, but they did not make it
to the tree yet, so I'm still attaching them here.

v5 changes:
 4/8 - patch updated by Peter with actual format definitions
       for x86 processors
 6/8 - added hardcoded terms for config[12] and sample_period
       the code is ready to include branch_sample_type once
       this field is available in perf_event_attr, just
       uncommenting one line.. ;) 
     - allow config option to be used without value in which
       case 1 is assigned as value

Overall summarize:
 - adding event parser bison/flex generator
 - the event syntax stays as it was
 - adding event format sysfs group attribute
   for pmu device
 - adding new syntax to specify raw events based
   on the sysfs pmu's format attribute
   eg. "cpu/config=1,config1=2,config2=3/u"

Attached patches:
 1/8 perf, tool: Remove unused functions from debugfs object
 2/8 perf, tool: Add sysfs mountpoint interface
 3/8 perf, tool: Add bitmap_or function into bitmap object
 4/8 perf: Adding sysfs group format attribute for pmu device
 5/8 perf, tool: Add parser generator for events parsing
 6/8 perf, tool: Add config options support for event parsing
 7/8 perf, tool: Add perf pmu object to access pmu format definition
 8/8 perf, tool: Add support to specify pmu style event

thanks,
jirka
